CSV to JSON

Convert CSV data to JSON format

How to use

1. Paste your CSV data (with a header row).
2. It's converted into a JSON array of objects.
3. Copy the JSON for your app, import, or API.

Why use this tool

• Header-aware: Uses the first row as keys so each row becomes a labelled object.
• Handles quoting: Respects quoted fields containing commas or line breaks.
• 100% private: Everything runs in your browser. Your data is never uploaded to a server, so it's safe for confidential content.

Frequently asked questions

Does my CSV need a header row?

Yes — the header row becomes the JSON keys. Without it, columns can't be labelled meaningfully.

Can it handle commas inside values?

Yes, as long as those values are wrapped in quotes, which is standard CSV.

Is my spreadsheet data uploaded?

No. Conversion runs in your browser, so private data stays on your device.
